Abstract: 1. Method of regulation fuel gas production from carbon-containing products, in particular waste and residues conditioned or processed in a suitable way by gasifying using gasifying agents, comprising air or gas mixture, containing oxygen wherein said carbon-containing products are introduced from above through the gasification apparatus and the gasification takes place in a charge of carbon-containing products mainly in the gasification zone above the grate, while the gasifying agent is fed as a mixed flow from the bottom through the grate and/or from above and also from the side into the gasification zone while fuel gas s drawn off above the upper level of the grate on the side opposite the lateral feed of the gasifying agent, wherein the main flow of the gasifying agent is fed on the side of the gasification zone and gasification process is regulated by the temperature profile of the gasification apparatus characterized in that: - vertical position of the principal gasification zone is adjusted by the velocity of ash discharge from the gasification apparatus, - optimum temperature of fuel gas formation is regulated by the flow of gasifying agent flow and mechanical consolidation of partially gasified charge, and - the output of the gasification apparatus is regulated by the width of the gasification zone through coordinated regulation of the gasifying agent feed and the ash discharge. 2. Apparatus of regulation fuel gas production from carbon-containing products, in particular waste and residues conditioned or processed in a suitable way by gasifying using gasifying agents, comprising air or gas mixture, containing oxygen wherein said carbon-containing products are introduced from above through the gasification apparatus and the gasification takes place in a charge of carbon-containing products mainly in the gasification zone above the grate, a mechanism is provided to feed the gasifying agent in a mixed flow from the bottom through the grate and/or from above and also from the side and drawn off on the side opposite the lateral feed of the gasifying agent, characterized in that in the gasification apparatus an inclined grate (1) with a drive to move it over for consolidating of already partially gasified charge in this zone. 3. Apparatus according to Claim 2 characterized in that the inclined grate is in the form of a step grate. 4. Apparatus according to one of Claims 2 or 3 characterized in that the gasification apparatus is enclosed in a double-layer insulating/cooling system layers of which are separated from each other by a perforated partition (8) wherein in the outer layer, being an insulating layer (7) and in the inner layer, being a cooling layer, holes are provided to feed the gasifying agents in the form of a cold combustible means into the outer layer and mainly through all surface of the perforated partition (8) into the inner layer and for drawing off as heated combustible means from the inner layer for further feed, at least through the lateral feeds (2) into the gasification apparatus.
